  1. 6. Methane oxidation over palladium oxide. From electronic structure to catalytic conversion

    Författare :Maxime van den Bossche; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; core-level spectroscopy; heterogeneous catalysis; PdO 101 ; palladium oxide; methane oxidation; microkinetic modelling; density functional theory;

    Sammanfattning : Understanding how catalysts work down to the atomic level can provide ways to improve chemical processes on which our contemporary economy is heavily reliant. The oxidation of methane is one such example, which is important from an environmental point of view. LÄS MER

  3. 7. Unravelling Sensitisation and Quenching Pathways in Lanthanide Luminophores

    Författare :Salauat Kiraev; Eszter Borbas; Thomas Just Sørensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lanthanide; Luminescence; Sensitisation; Quenching; Energy Transfer; Electron transfer; Kemi; Chemistry;

    Sammanfattning : Lanthanide (Ln) ions find use in cellular detection and probing of many analytes, owing to their unique photophysical properties. However, to make the Ln emission efficient, one has to develop a light-harvesting antenna, which is an organic chromophore that absorbs and transfers energy to the Ln. LÄS MER

  4. 8. Development of Polyamide Solvent Extraction Reagents for Trivalent Lanthanides

    Författare :Mikhail S Tyumentsev; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyamides; Solvent Extraction; Europium; Rare Earth Elements; Lanthanides; Malonamides;

    Sammanfattning : Rare earth elements (REEs), including lanthanides, are critical materials for many industrial technologies. As a result recycling of end-of-life products containing REEs might be beneficial, as this could partially satisfy the growing demands of industry for these elements. LÄS MER

  5. 9. Experimental and quantum-chemical studies of the surface interactions between organic molecules and nanocrystals of (a) RE2O3 (RE = Y or Gd); and (b) TiOb2

    Författare :Henrik Pedersen; Per-Olov Käll; Lars-Johan Norrby; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The increasing interest for using nanocrystals in bio-medical and optical applications has highlighted the need of molecular functionalisation of nanocrystals. Knowledge of how to attach molecules to the nanocrystal surface is a key factor. LÄS MER

  7. 10. Highly Efficient CIGS Based Devices for Solar Hydrogen Production and Size Dependent Properties of ZnO Quantum Dots

    Författare :T. Jesper Jacobsson; Tomas Edvinsson; Laurence Peter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanoparticles; Quanum Dots; Size Dependent Properties; Hematite; CIGS; Solar Water Splitting; Hydrogen Production; PEC; Photoelectrochemical cells; PV-electrolysis; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Materials and device concepts for renewable solar hydrogen production, and size dependent properties of ZnO quantum dots are the two main themes of this thesis.ZnO particles with diameters less than 10 nm, which are small enough for electronic quantum confinement, were synthesized by hydrolysis in alkaline zinc acetate solutions.
